Altius L1¶
Altius L1 is the institutional EVM base layer of the Altius Stack. It is built on a modern, Reth-based execution stack and a fast Byzantine-fault-tolerant (BFT) consensus, and it is fully EVM-compatible (Prague) — existing smart contracts, developer tooling, and wallets work without modification.
What sets it apart from a general-purpose chain is an operator control plane: the network is designed to be run by regulated and enterprise operators, with first-class support for configurable fees, governance, validator management, and auditable administration.
Highlights¶
- Full EVM compatibility (Prague) — standard contracts, ABIs, JSON-RPC, and tooling work unchanged.
- Fast, deterministic finality — a fixed-interval BFT consensus produces blocks on a sub-second cadence with deterministic finalization.
- Modern execution stack — built on Reth, with the EVM provided through the Alloy ecosystem.
- Institutional control plane — configurable fee tokens, on-chain governance, a managed validator lifecycle, role-based administration, and audit logging. See Institutional Control Plane.
- Designed to scale — integrates with the SSMT engine to keep state-root computation off the critical path as state grows.
How it fits the platform¶
Altius L1 is the settlement layer of the Altius platform. Applications interact with it over standard EVM JSON-RPC, and Altius HPEC uses it as its L1, periodically settling verified execution results to the chain.
